Performance gains / why it is needed

Stock rubber bushes flex under cornering and braking causing vague steering and understeer. Solid offset caster bushes lock the geometry in place, so steering is more precise, braking is more stable and tyre contact patch is improved during cornering. They let you run higher positive caster and maximum camber from adjustable top mounts without wheel arch rub.
